Abstract
Systems and methods for creating glass and ceramic fibers comprising mixed properties are disclosed. In some embodiments, a first material and a second material are fused in a cane drawing process to generate fibers. The first material and the second material may comprise different coefficient of thermal expansion (CTE) properties. Upon heating and/or cooling the fused material, a first portion and a second portion of the fused material expand/contract at different rates generating/relieving stresses in the fused material. Furthermore, the first portion and second portion may be provided in contact with, or bonded to, various metals or other materials to produce hermetic seals.
Claims20
A method of creating a fused material with a coefficient of thermal expansion (CTE) functional gradient, the method comprising:
- providing a first material and a second material,
- wherein the first material comprises a first coefficient of thermal expansion (CTE) and the second material comprises a second CTE and the first CTE is distinct from the second CTE;
- adding heat to the first material and the second material to fuse the first material to the second material and drawing the first material and the second material into the fused material,
- wherein the fused material comprises a first portion comprising a first portion CTE, and a second portion comprising a second portion CTE;
- providing one or more holes in the fused material;
- and
- providing one or more tubes in the one or more holes.
A method of creating a fused material with a coefficient of thermal expansion (CTE) functional gradient, the method comprising:
- providing a first material and a second material,
- wherein the first material comprises a first CTE and the second material comprises a second CTE and the first CTE is distinct from the second CTE,
- wherein a first material geometry is a rod, and a second material geometry is a tube, and the method further comprises inserting the rod into the tube;
- adding heat to the first material and the second material to fuse the first material to the second material;
- drawing the first material and the second material into the fused material comprising a cane or a fiber,
- wherein the fused material comprises a first portion comprising a first portion CTE, and a second portion comprising a second portion CTE;
- forming at least one hole in the first portion;
- and
- inserting at least one metal tube into the at least one hole, wherein a metal CTE of the at least one metal tube is similar to the first portion CTE.
A method of creating a fused material with a coefficient of thermal expansion (CTE) functional gradient, the method comprising:
- providing a first material and a second material,
- wherein the first material and the second material comprise a glass, a ceramic, or a glass ceramic,
- wherein the first material comprises a first CTE and the second material comprises a second CTE and the first CTE is distinct from the second CTE;
- adding heat to the first material and the second material to fuse the first material to the second material;
- drawing the first material and the second material into the fused material,
- wherein the fused material comprises a first portion comprising a first portion CTE based on the first CTE, a second portion comprising a second portion CTE based on the second CTE;
- providing one or more holes in the first portion of the fused material;
- inserting one or more tubes into the one or more holes;
- and
- bonding the one or more tubes to the first portion.
